Abstract

Des techniques permettant de localiser des points d'accès et des terminaux dans des réseaux locaux sans fil (WLAN) et dans d'autres réseaux sans fil. Pour localiser des points d'accès, des mesures sont obtenues pour au moins un point d'accès présent dans un WLAN. Ces mesures peuvent être fondées sur des séquences de transmission (par exemple des trames de balise) envoyées périodiquement par chaque point d'accès. Les mesures peuvent être effectuées par plusieurs terminaux situés à des endroits différents ou par un seul terminal mobile situé à différents endroits. La localisation de chaque point d'accès est déterminée sur la base des mesures et des emplacements connus du terminal ou des terminaux. Pour la localisation d'un terminal, des mesures d'au moins un point d'accès dans un WLAN sont obtenues. La localisation du terminal est déterminée sur la base des mesures et de l'emplacement connu de chaque point d'accès. Les mesures peuvent être des mesures du temps de parcours, des mesures de différence des temps observés, des mesures du temps d'arrivée, des mesures d'intensité du signal, des mesures de la qualité du signal et autres.
